NOLAG

ok so basically i have a bottom mount gt28 setup ,went ahead and bought the jgs oil return kit.due to the location i have the bung as seen below ,when i use the nice blue silicone hose they give you it kinks(due to me retaining AC).im currently using a high temp heater core hose for a temp. fix but ithink its backing up oil.i made my own fitting with a 90 degree elbow to fit in the bung out of copper,but cant get it to spin even one full turn due to it hitting things.so basically im looking for a fitting (90 degree type)that i can thread in this bung that wont spin untill it starts to get tight.just like the oil feed works.if some one can find me the fitting i will paypal you 5 bucks .thanks btw not sure of the thread pitch i beleive its half an inch though.
